Klimahaus 8\u00b0 East, Bremerhaven<\/h1>\n[\/vc_column_text][vc_column_text css=”.vc_custom_1655626493716{padding-top: 10px !important;}”]\n

In mid-2009, the Klimahaus (climate house) 8\u00b0 East opened in the middle of Bremerhaven’s maritime centre, exactly where Bremerhaven was founded in 1827, at 8\u00b0 east longitude. The Klimahaus, in the form of a pneumatic raft, houses 143 exhibition rooms that visualise the environmental areas of climate, weather and landscape as the basis of life. Visitors “travel” around the earth on the eighth eastern longitude and learn about the different climate zones. The total area of the climate house, which is over 30 m high, consists of the inner load-bearing structure in solid construction (concrete), the roof covering of trapezoidal sheet metal, thermal insulation and standing seam roof, as well as the fa\u00e7ade of 4,700 differently shaped laminated glass panes. A steel structure supports both the roof and the fa\u00e7ade and also includes other small steel assemblies such as the central access with ring-shaped walkways, cubes and the technical centre with visitor terrace.<\/p>\n

Fire and corrosion protection<\/h2>\n

For this steel construction, appropriate fire and corrosion protection is required that meets the special requirements during the construction and use phases over decades. This protection must meet several requirements: It should be applicable in as few layers as possible with a high corrosivity category, thus have a low total layer thickness with nevertheless fast drying and be environmentally compatible, i.e. with few so-called volatile organic substances. After additional consideration of the costs, functionality and service life of the coating, the decision was made in favour of the corrosion protection system from Sika, the manufacturer of the intended fire protection system.\u00a0This involves coating the entire 65,000 m\u00b2 steel structure with an actively pigmented primer, which is applied in the required wet film thickness.\u00a0Without this permanent corrosion protection, weathering or chalking behind the glass panes or delamination between the individual layers occurs after only a short period of exposure in building projects such as the Klimahaus under light-resistant top coats on the fa\u00e7ade beams.<\/p>\n[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column width=”1\/3″ css=”.vc_custom_1585075122186{margin-bottom: 20px !important;}”][vc_column_text]\n

Critical surfaces had to be coated with the fire protection system “Sika Unitherm LSA” before the top coat in order to meet the object-specific climatic requirements in the fire resistance class F30 Ab. Only this system fulfils all three fire resistance classes (F30\/F60\/F90), depending on the solidity and dry film thickness. The advantage of the new fast-drying reactive intumescent is above all the “Unitherm” coating, which forms a well-insulating foam when heat is generated from 180\u00b0-200\u00b0 C. This foam is about 40-50 times thicker than the original coating. This is about 40-50 times thicker than its original layer and causes the temperature of 500\u00b0C, which is decisive for the loss of load-bearing capacity of steel components, to be reached only after a delay of at least 30 minutes. Another advantage is the appearance; the fire protection coatings are smooth and differ only minimally from the top coats for corrosion protection.<\/p>\n

The Klimahaus 8\u00b0 Ost deals with the topic of climate protection in a diverse and vivid way and thus meets the political and social challenge by explaining and drawing attention to climate change worldwide.<\/p>\n[\/vc_column_text][\/vc_column][vc_column width=”2\/3″ css=”.vc_custom_1585075094131{margin-bottom: 0px !important;}”][vc_empty_space height=”10px”]
